When disasters strike, pre- and post-event imagery can provide critical information regarding the extent, severity, and evolution of the event.
USGS Emergency Response supports the coordination of remotely sensed data acquisitions and distribution of images and geospatial information products to aid in disaster response operations. This activity is based at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.
Over the past decade, USGS has supported the response to hundreds of domestic and international disaster events. USGS provides access to remotely sensed imagery and geospatial datasets in response to requests from agencies engaged in disaster response. One agency may submit the initial request for support, but the imagery that becomes available on HDDS can be shared across the response community.
